Wow thx. I just started trig as a freshman and I couldn’t understand it at all. I’ll be sure to save this lol
Answer:
The area of the triangle is 351cm^2.
Step-by-step explanation:
To find the area of a triangle, the formula is (1/2) x base x height. In this case, the height would be a line that cuts straight through the center of the triangle. However, this height is not given to us. We can still find it through Pythagoras' Theorem though.
Let A be the tip of the triangle, and B and C be the points on either side of the triangle. Assuming an imaginary line that cuts the triangle in a symmetrical half, let T be the point at the end of the line, directly below point A.
Using Pythagoras' Theorem,
AB^2 = AT^2 + TB^2
AT^2 = AB^2 - TB^2
AT^2 = 30^2 - (26/2)^2
AT^2 = 30^2 - 13^2
AT =
AT = 27.0370116692
So the length of AT is our height. We can now find the area of the triangle.
Area of triangle = (1/2) x 26cm x AT
Area of triangle = 351.4811516996
Area of triangle = 351cm^2 (To 3s.f.)
Answer:
yes (at about (22, 66)
Step-by-step explanation:
If you subtract 3 times the horizontal distance, the equation becomes ...
yv -yh = (0.006x^3 -0.06x^2+1.4x) -(3x) = 0.006x^3 -0.06x^2 -1.6x
The signs of the terms are +--, so Descartes' rule of signs tells us the one sign change indicates one positive real root. That is this difference will be zero for some positive value of x.
Yes, it is possible.
